/**
|

* struct rtnl_link_stats64 - The main device statistics structure.
|
||||
*
|
||||
* @rx_packets: Number of good packets received by the interface.
|
||||
* For hardware interfaces counts all good packets received from the device
|
||||
* by the host, including packets which host had to drop at various stages
|
||||
* of processing (even in the driver).
|
||||
*
|
||||
* @tx_packets: Number of packets successfully transmitted.
|
||||
* For hardware interfaces counts packets which host was able to successfully
|
||||
* hand over to the device, which does not necessarily mean that packets
|
||||
* had been successfully transmitted out of the device, only that device
|
||||
* acknowledged it copied them out of host memory.
|
||||
*
|
||||
* @rx_bytes: Number of good received bytes, corresponding to @rx_packets.
|
||||
*
|
||||
* For IEEE 802.3 devices should count the length of Ethernet Frames
|
||||
* excluding the FCS.
|
||||
*
|
||||
* @tx_bytes: Number of good transmitted bytes, corresponding to @tx_packets.
|
||||
*
|
||||
* For IEEE 802.3 devices should count the length of Ethernet Frames
|
||||
* excluding the FCS.
|
||||
*
|
||||
* @rx_errors: Total number of bad packets received on this network device.
|
||||
* This counter must include events counted by @rx_length_errors,
|
||||
* @rx_crc_errors, @rx_frame_errors and other errors not otherwise
|
||||
* counted.
|
||||
*
|
||||
* @tx_errors: Total number of transmit problems.
|
||||
* This counter must include events counter by @tx_aborted_errors,
|
||||
* @tx_carrier_errors, @tx_fifo_errors, @tx_heartbeat_errors,
|
||||
* @tx_window_errors and other errors not otherwise counted.
|
||||
*
|
||||
* @rx_dropped: Number of packets received but not processed,
|
||||
* e.g. due to lack of resources or unsupported protocol.
|
||||
* For hardware interfaces this counter may include packets discarded
|
||||
* due to L2 address filtering but should not include packets dropped
|
||||
* by the device due to buffer exhaustion which are counted separately in
|
||||
* @rx_missed_errors (since procfs folds those two counters together).
|
||||
*
|
||||
* @tx_dropped: Number of packets dropped on their way to transmission,
|
||||
* e.g. due to lack of resources.
|
||||
*
|
||||
* @multicast: Multicast packets received.
|
||||
* For hardware interfaces this statistic is commonly calculated
|
||||
* at the device level (unlike @rx_packets) and therefore may include
|
||||
* packets which did not reach the host.
|
||||
*
|
||||
* For IEEE 802.3 devices this counter may be equivalent to:
|
||||
*
|
||||
* - 30.3.1.1.21 aMulticastFramesReceivedOK
|
||||
*
|
||||
* @collisions: Number of collisions during packet transmissions.
|
||||
*
|
||||
* @rx_length_errors: Number of packets dropped due to invalid length.
|
||||
* Part of aggregate "frame" errors in `/proc/net/dev`.
|
||||
*
|
||||
* For IEEE 802.3 devices this counter should be equivalent to a sum
|
||||
* of the following attributes:
|
||||
*
|
||||
* - 30.3.1.1.23 aInRangeLengthErrors
|
||||
* - 30.3.1.1.24 aOutOfRangeLengthField
|
||||
* - 30.3.1.1.25 aFrameTooLongErrors
|
||||
*
|
||||
* @rx_over_errors: Receiver FIFO overflow event counter.
|
||||
*
|
||||
* Historically the count of overflow events. Such events may be
|
||||
* reported in the receive descriptors or via interrupts, and may
|
||||
* not correspond one-to-one with dropped packets.
|
||||
*
|
||||
* The recommended interpretation for high speed interfaces is -
|
||||
* number of packets dropped because they did not fit into buffers
|
||||
* provided by the host, e.g. packets larger than MTU or next buffer
|
||||
* in the ring was not available for a scatter transfer.
|
||||
*
|
||||
* Part of aggregate "frame" errors in `/proc/net/dev`.
|
||||
*
|
||||
* This statistics was historically used interchangeably with
|
||||
* @rx_fifo_errors.
|
||||
*
|
||||
* This statistic corresponds to hardware events and is not commonly used
|
||||
* on software devices.
|
||||
*
|
||||
* @rx_crc_errors: Number of packets received with a CRC error.
|
||||
* Part of aggregate "frame" errors in `/proc/net/dev`.
|
||||
*
|
||||
* For IEEE 802.3 devices this counter must be equivalent to:
|
||||
*
|
||||
* - 30.3.1.1.6 aFrameCheckSequenceErrors
|
||||
*
|
||||
* @rx_frame_errors: Receiver frame alignment errors.
|
||||
* Part of aggregate "frame" errors in `/proc/net/dev`.
|
||||
*
|
||||
* For IEEE 802.3 devices this counter should be equivalent to:
|
||||
*
|
||||
* - 30.3.1.1.7 aAlignmentErrors
|
||||
*
|
||||
* @rx_fifo_errors: Receiver FIFO error counter.
|
||||
*
|
||||
* Historically the count of overflow events. Those events may be
|
||||
* reported in the receive descriptors or via interrupts, and may
|
||||
* not correspond one-to-one with dropped packets.
|
||||
*
|
||||
* This statistics was used interchangeably with @rx_over_errors.
|
||||
* Not recommended for use in drivers for high speed interfaces.
|
||||
*
|
||||
* This statistic is used on software devices, e.g. to count software
|
||||
* packet queue overflow (can) or sequencing errors (GRE).
|
||||
*
|
||||
* @rx_missed_errors: Count of packets missed by the host.
|
||||
* Folded into the "drop" counter in `/proc/net/dev`.
|
||||
*
|
||||
* Counts number of packets dropped by the device due to lack
|
||||
* of buffer space. This usually indicates that the host interface
|
||||
* is slower than the network interface, or host is not keeping up
|
||||
* with the receive packet rate.
|
||||
*
|
||||
* This statistic corresponds to hardware events and is not used
|
||||
* on software devices.
|
||||
*
|
||||
* @tx_aborted_errors:
|
||||
* Part of aggregate "carrier" errors in `/proc/net/dev`.
|
||||
* For IEEE 802.3 devices capable of half-duplex operation this counter
|
||||
* must be equivalent to:
|
||||
*
|
||||
* - 30.3.1.1.11 aFramesAbortedDueToXSColls
|
||||
*
|
||||
* High speed interfaces may use this counter as a general device
|
||||
* discard counter.
|
||||
*
|
||||
* @tx_carrier_errors: Number of frame transmission errors due to loss
|
||||
* of carrier during transmission.
|
||||
* Part of aggregate "carrier" errors in `/proc/net/dev`.
|
||||
*
|
||||
* For IEEE 802.3 devices this counter must be equivalent to:
|
||||
*
|
||||
* - 30.3.1.1.13 aCarrierSenseErrors
|
||||
*
|
||||
* @tx_fifo_errors: Number of frame transmission errors due to device
|
||||
* FIFO underrun / underflow. This condition occurs when the device
|
||||
* begins transmission of a frame but is unable to deliver the
|
||||
* entire frame to the transmitter in time for transmission.
|
||||
* Part of aggregate "carrier" errors in `/proc/net/dev`.
|
||||
*
|
||||
* @tx_heartbeat_errors: Number of Heartbeat / SQE Test errors for
|
||||
* old half-duplex Ethernet.
|
||||
* Part of aggregate "carrier" errors in `/proc/net/dev`.
|
||||
*
|
||||
* For IEEE 802.3 devices possibly equivalent to:
|
||||
*
|
||||
* - 30.3.2.1.4 aSQETestErrors
|
||||
*
|
||||
* @tx_window_errors: Number of frame transmission errors due
|
||||
* to late collisions (for Ethernet - after the first 64B of transmission).
|
||||
* Part of aggregate "carrier" errors in `/proc/net/dev`.
|
||||
*
|
||||
* For IEEE 802.3 devices this counter must be equivalent to:
|
||||
*
|
||||
* - 30.3.1.1.10 aLateCollisions
|
||||
*
|
||||
* @rx_compressed: Number of correctly received compressed packets.
|
||||
* This counters is only meaningful for interfaces which support
|
||||
* packet compression (e.g. CSLIP, PPP).
|
||||
*
|
||||
* @tx_compressed: Number of transmitted compressed packets.
|
||||
* This counters is only meaningful for interfaces which support
|
||||
* packet compression (e.g. CSLIP, PPP).
|
||||
*
|
||||
* @rx_nohandler: Number of packets received on the interface
|
||||
* but dropped by the networking stack because the device is
|
||||
* not designated to receive packets (e.g. backup link in a bond).
